PTGDS is a potential marker for lung adenocarcinoma identified in a pancancer analysis.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Prostaglandin D2 synthase (PTGDS) is the enzyme responsible for synthesizing prostaglandin D2. Despite its crucial role, PTGDS remains relatively understudied in tumor therapy, and comprehensive pancancer analyses are lacking. By leveraging multiomics data integration, this study elucidated the widespread dysregulation of PTGDS across various cancers and its correlation with patient survival. Moreover, PTGDS is significantly associated with stem cell scores, microenvironmental scores, microsatellite instability (MSI) status, tumor mutational burden (TMB), and methylation status in diverse tumor types. Additionally, immune correlations with PTGDS are evident across most cancers, with single-cell transcriptome data indicating predominant associations with natural killer cells and macrophages. Notably, experimental validation revealed the role of PTGDS in inhibiting A549 and H1975 lung adenocarcinoma cell proliferation, which was mediated by fatty acid degradation and cell cycle regulation. In summary, PTGDS has prognostic potential, influences pancancer tumor immunity, and acts as a tumor suppressor in lung adenocarcinoma (LUAD).
